Application of superfine inorganic fiber spraying products in building energy efficiency

超细无机纤维棉经专用喷涂设备造粒、喷吹后与雾化的粘结剂在喷枪前端40厘米左右处充分混合后，均匀喷覆于建筑基体表面，经人工整形和自然干燥后形成具有连续无空腔、无接缝、无冷桥、A级防火性能的保温层，简称为无机纤维喷涂。

Ultrafine inorganic fiber cotton granulated by special spraying equipment, sprayed with atomized binder in the spray gun front 40 cm or so after full mixing, evenly sprayed on the surface of the building substrate, after artificial shaping and natural drying to form a continuous cavity-free, seamless, no cold bridge, class A fire insulation layer, referred to as no Machine fiber spraying.

无机纤维喷涂保温产品以其优异的防火、保温、吸声和针对异型结构无障碍喷涂施工的特点，被广泛应用于建筑节能保温工程中，施工流程如图1所示。随着无机纤维喷涂保温的广泛普及，建筑市场也对无机纤维喷涂层外观装饰性提出了更高的要求。

Inorganic fiber spraying insulation products are widely used in building energy-saving and thermal insulation projects because of their excellent fire protection, insulation, sound absorption and barrier-free spraying for special-shaped structures. The construction process is shown in Figure 1. With the wide spread of inorganic fiber spraying insulation, the building market also put forward higher requirements for the appearance of inorganic fiber spraying coating decoration.

基于纤维喷涂产品表面蓬松，尤其是室内顶板施工技术的良莠不齐，导致不能达到质量标准，后期出现了纤维掉屑、色差变大、浮尘吸附等现象，极大地影响建筑室内的美观。

Based on the fluffy surface of fiber spraying products, especially the uneven construction technology of indoor roof, it can not meet the quality standards. In the later period, fiber chip dropping, color difference becoming larger, floating dust adsorption and other phenomena appeared, which greatly affected the beauty of the building interior.

2.2 保温绝热

2.2 thermal insulation

无机纤维喷涂完成后经过自然干燥后形成表面平整、纤维分布均匀、结构密闭、连续无接缝、无冷桥、具有弹性皮肤似的保温层；使用无机纤维喷涂后从根本上解决了传统材料（岩棉、玻璃棉、聚苯板、挤塑板等板材）密闭性差、接缝多、冷桥多，与基层墙体不能满粘，安装工序复杂、尺寸变形大等问题。

Inorganic fiber spraying after the completion of natural drying to form a smooth surface, uniform fiber distribution, closed structure, continuous seamless, no cold bridge, with elastic skin-like insulation layer; the use of inorganic fiber spraying after the fundamental solution to the traditional materials (rock wool, glass wool, polystyrene board, extruded board, etc.) airtightness There are many problems, such as poor, many joints, many cold bridges, not fully adhered to the base wall, complex installation procedures, large size deformation and so on.

2.3 吸声降噪

2.3 sound absorption and noise reduction

超细无机纤维经特殊喷涂工艺施工后，其内部纤维交织在一起，形成具有一定强度和韧性的三维立体网状结构，极大地延长了声波在其内部的传播路径和时间，进而增加了因声波使纤维振动而引发的声能向机械能转换时间，使遇到纤维喷涂层的声波能量急剧衰减，因而具有良好的吸声性能。

Ultrafine inorganic fibers are interwoven by special spraying technology to form a three-dimensional network structure with certain strength and toughness, which greatly lengthens the propagation path and time of sound waveszengyab.75ix.com huagongb.75ix.com nongjiangb.75ix.comzhujiangb.75ix.com mifengj.75ix.commifeng.75ix.com  in the interior of the fiber, and then increases the time for the conversion of sound energy to mechanical energy caused by the vibration of the fiber caused by sound waves. The acoustic energy of the fiber sprayed layer is rapidly attenuated and has good sound absorption property.

2.4 异形结构适应性

2.4 heteromorphic structure adaptability

现场喷涂的施工工艺可满足设计师的设计随意性，适应任何复杂结构及异型结构的原状态，解决了传统的支撑、吊挂件和加固材料的复杂工序，即使是施工人员很难到达的空间例如管线、吊挂件、密集区域，均可轻松喷涂施工。喷涂棉与岩棉、玻璃棉类产品的保温性能无太大差别，但板材类保温产品采用点框粘和膨胀锚栓的施工方式，保温层与墙体间存在多处间隙，板材拼接处存在大量的板缝，对墙体异性结构处理工序繁杂，喷涂棉现场喷涂工艺技术则完全贴合基层墙体，连续喷涂无任何接缝，在平整墙面、异型结构处理上有先天优势。

The on-site spraying technology can satisfy the designer's randomness, adapt to the original state of any complex structure and special-shaped structure, and solve the complex process of traditional support, hanging parts and reinforcement materials. Even the space which is difficult for construction personnel to reach, such as pipeline, hanging parts and dense area, can be sprayed easily. . Spraying cotton and rock wool, glass wool products insulation performance is not much different, but the board insulation products using point frame sticking and expansion anchor bolt construction, insulation layer and wall there are many gaps, there are a lot of plate joints, the wall of heterogeneous structure processing procedures are complex, spraying cotton on-site spraying technology The technique is completely adhered to the base wall, continuous spraying without any seams, in the flat wall, special-shaped structure treatment has a congenital advantage.

喷涂棉长期使用不收缩、不卷曲、不塌陷、不脱落，是一种专门针对幕墙保温的喷涂新技术。

Spraying cotton is a new spraying technology for curtain wall insulation, which can not shrink, curl, collapse and fall off for a long time.
